DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 The intelligent non-negative pressure variable frequency constant pressure water supply equipment includes an equipment body 1 and a support plate 2. The equipment body 1 is the intelligent non-negative pressure variable frequency constant pressure water supply equipment. The support plate 2 is the supporting component of the equipment body 1. The equipment body 1 is a prior art product, and its specific structure will not be described here. This solution only improves the part that raises the problem.

[0022] A bottom groove 3 is provided on the bottom wall of the support plate 2, a mounting block 4 is provided on the support plate 2, a rotating frame 5 is rotatably provided on the mounting block 4, a moving wheel 6 is installed on the rotating frame 5, rotating grooves 7 are provided on the inner walls on both sides of the bottom groove 3, a double-headed screw 8 is provided in the rotating groove 7 through a driving motor 14, a nut 9 is threadedly sleeved on the double-headed screw 8, a mounting frame 10 is provided on the nut 9 through a synchronization mechanism, the mounting frame 10 is connected to the rotating frame 5 through a rotating mechanism, a toggle groove 12 is provided on the mounting frame 10, a slide rod 18 is provided in the toggle groove 12, a limit plate 13 is slidably sleeved on the slide rod 18 through an elastic mechanism, and a limit groove corresponding to the limit plate 13 is provided on the inner wall of the rotating groove 7.

[0023] The synchronization mechanism includes a synchronization block 16 installed on the outer wall of the nut 9. The mounting frame 10 is U-shaped and has a synchronization groove 17 on the surface in contact with the nut 9. When the synchronization block 16 is in the synchronization groove 17, the nut 9 moves on the double-headed screw 8, and the synchronous movement of the mounting frame 10 can be achieved.

[0024] The rotating mechanism includes a rack 11 installed on the mounting frame 10, and a gear 20 meshing with the rack 11 is provided on the rotating frame 5. When the rack 11 moves with the mounting frame 10, it drives the gear 20 to rotate, thereby driving the rotating frame 5 to rotate and changing the support height of the support plate 2.

[0025] The elastic mechanism includes a spring 19 sleeved on the outside of the slide rod 18, and the two ends of the spring 19 are elastically connected to the outer wall of the limit plate 13 and the inner wall of the toggle slot 12 respectively. The elastic potential energy provided by the spring 19 realizes the extrusion of the limit plate 13, ensuring that its vertical part is in the limit slot on the inner wall of the rotating slot 7, thereby preventing the mounting frame 10 from detaching from the nut 9.

[0026] A limit rod 15 is provided in the rotating groove 7 , and the limit rod 15 is parallel to the double-headed screw 8 . The limit rod 15 slides through the nut 9 , and the limit rod 15 limits the nut 9 to prevent it from rotating with the double-headed screw 8 .

[0027] The vertical cross-section of the limiting plate 13 is L-shaped, and the moving wheel 6 is a universal wheel, which facilitates the multi-directional movement of the entire device.

[0028] When the utility model is used, when the equipment body 1 needs to be moved, the locking button on the moving wheel 6 is opened, and the support plate 2 can be pushed at any time with the help of the moving wheel 6 to realize the moving operation of the equipment body 1. During the movement, when the ground is relatively rugged and the height of the support plate 2 needs to be adjusted, the driving motor 14 is started at this time to drive the double-headed screw 8 to rotate. When the double-headed screw 8 rotates, the nut 9 threadedly installed thereon will drive the mounting frame 10 to move, and the mounting frame 10 cooperates with the rack 11 to drive the gear 20 to rotate, thereby realizing the rotation of the rotating frame 5 and changing its inclination angle, thereby realizing the height change of the support plate 2.

[0029] When the height of the support plate 2 changes, the height of the equipment body 1 will also change. When inspecting and maintaining, the height can be adjusted to accommodate the operation of maintenance personnel of different heights.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
